a This is a self—hybridization, which serves as a measure of experimental error (see Methods).

b The number of differentially expressed genes with an FDR of 0.05 according to the single-species array analysis (in parentheses, the percentage from all genes studied).

c The number of genes that were found to be differentially expressed by the single-species analysis, but not when probe sets from both species were considered.

d The number of differentially expressed genes with an FDR of 0.05 according to the multi-species array analysis.

e The number of genes that were found to be differentially expressed when probe sets from both species were considered, but not by the single-species array analysis.
